I dont have any problems with extension, like I can extend it fully to the point where it feels like it will go inside out, its mainly flexion, I have a little trouble getting it flexed fully.

Im getting an ACL brace, so hopefully I can try to play sport, as I would like to wait until the seasons over for surgery, if that would be possible or will it still feel unstable and wear down the cartilage?

Thanks for the info
